Joe Simpson has committed his future to Wasps, signing a new long term deal at the Premiership club.
The 24-year-old scrum-half has made 105 appearances for the Wycombe-based team since making his debut five years ago.
Wasps Director of Rugby Dai Young told the club's website. "He already is a very good player but I believe there is a lot more to come from him.
"We've got a core of young English talent here and Joe is at the heart of that.
"He's achieved a lot for his age but he's got the ability and talent to achieve lots more as a Wasps player."
Simpson added. "I am delighted to sign a new contract. Wasps is my home town club and the club I grew up supporting.
"I am excited about the future that we have here on and off the field. Some of our best players here haven't even reached their prime yet and we've got a squad which is nowhere near its peak yet.
"We've got a great coaching set up here and the right man in charge in Dai Young who is taking us in a great direction. Dai is very well respected and well liked here and I really enjoy working with him."
